Other streptococcal arthritis, right shoulder

This code signifies an inflammatory joint condition affecting the right shoulder, specifically caused by a streptococcal bacterial infection, but not classified as a primary or post-infectious reactive arthritis. It indicates the presence of an active infection within the joint space.

Apply this code when documentation clearly states streptococcal arthritis of the right shoulder, excluding cases explicitly identified as primary pyogenic arthritis or reactive arthritis. Supporting documentation should include positive streptococcal cultures from synovial fluid or blood, or a definitive clinical diagnosis of streptococcal etiology.

• Ensure documentation specifies "other" streptococcal arthritis to differentiate from primary pyogenic or reactive forms.
• Verify laterality (right shoulder) is explicitly stated in the clinical notes.
• Consider sequencing this code after a code for the underlying streptococcal infection, if applicable, following ICD-10-CM guidelines.
